|Feel free to believe your eyes: According to the National Weather Service of Amarillo, Texas, this picture is the real thing. Between 3 and 4 p.m. CDT on Wednesday, April 11, 2012 a storm dumped massive amounts of pea-sized ice balls about 25 miles north of Amarillo. Wind and subsequent rains carved the hail into drifts four feet high, as seen here with a member of the Potter County Fire Department. [See more amazing science images]|

|A young star called Formalhaut that is home to at least one alien planet is also ringed by a vast, dusty cloud of comets, like our own solar system. But there's a big difference: There may be as many as 83 trillion comets there, with collisions destroying thousands each day, a new study suggests. [Read full story]|

New research reported this week reveals why it's good to get naked for some organisms. The study found the moulting process, in which crustaceans and insects lose their exoskeleton in order to form a new one may actually protect moulting animals from parasites. Shown here, a water flea (Daphnia magna) undergoes moulting. Like all crustaceans, this tiny creature must moult to grow. [Read full story]
|7. A Dinosaur at Sunset|
|A palaeontologist-artist has revealed what a meat-eating dinosaur called Unenlagia (whose name means "half-bird") may have looked like when it roamed the Earth some 85 million years ago during the late Cretaceous. [Read full story]|
